Packets are somethings like Commands and messages are sent from Server To Client or Client To Server.. Something like when you enter a channel.. The Client send to the server that it wants to enter the Channel, so the Server Send it back the information of Rooms "Ids, passwords, .. etc".. but They are in Hex + Encrypted packets!

So you can see them like "C3 D3 00 A5 AA A3 00 00 00 00 0C 00 F3 00 00" ... etc!

So you will need to analysis packets to get from them the Id of the packets and Packet size.. etc.
How will you get benefit from these?
First you need to be coder << so you can send and receive them, if you are coder, how can you benefit them!
It's easy, some of these packets you can change their values to get some ******* fake things.. and true things!

xD
I hope that you understand!
